Zenith Chromacolor II (Ch. 19EC45) 19" color tabletop TV repair log

[Tim Tress]

I worked on dozens of them, when they were relatively new. Two other components to check; the damper diode under the horizontal output socket, and the feedthrough capacitor in the collector circuit of that transistor. For a quick check of the tripler, disconnect the output lead of the flyback transformer from the tripler, making sure to space the wire well away from anything that it could arc to. Apply power; if the breaker now holds, the tripler is shorted.

Also check the electrolytic capacitor and the rectifier diodes for shorts.

I have many modules for that chassis, if you should need any.
